MACHINE FOR COILING WIRE.

SPECIFICATION forming part of Letters Patent No. 230,123, dated July 20, 1880.

Application filed March 17, 1880. (No model.)

To all whom it may concern: 7

Be it known that I, GEORGE GALE, a citi-. zen of Canada, residing at Stanstead,- in the county of Stanstead and Province of Quebec, have invented certain'new and useful Improvements in Machines for Ooiling Wire; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines for coiling wire for springs, flexible be applied, and has for its object the coiling of annealed steel or iron wire, also that which is unannealed, the coils of which may be open or closed, and whose length is limited only by the length of the wire; to increase or decrease the size of the coil within certain limits without changing the spindle; to adjust the pitch of the coils while the machine is in motion; to adapt the coiler to an ordinary lathe; to means for simple and rapid change of the wearing parts. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the machine. Fig. 2 is an end elevation of the same, showing that end which is at the left in Fig. 1, a part being represented as broken away to more fully show the construction. Fig. 3 is a detailed view of the shaft, coupling, and coiling devices; and Fig. 4 is a vertical section of the The base A is surmounted by two vertical standards, B, in the tops of which the shaftF has its bearings, The post 0 is adjustably secured to the base A, as clearly shown in Figs. 1 and 2 of the drawings. One end of the sh aft F carries a coupling, G, which serves to couple the spindle a thereto, being secured by means of the set-screws m n. The spindle a is inclosed by the die a, which projects into and is secured to the tool-carrier E by the/set-screw g. The die 0 is provided with a spiral face, its central cavity or eye being enlarged toward the opposite face, as shown in Fig. 4, the purpose of which will presently be explained.

Mounted on a post, D, is the reel H, provided with fingers f, upon which the wire to be coiled may be placed. One end of the wire is passed under the grooved pulley (l, which is mounted in the inclined frame I). The wire is then wound several turns about the spindle a in the direction in which the shaft F revolves, when the machine is ready to work.

Referring to Fig. 2, the handle I, Fig.1,- is

- turned in the direction of the arrow, the shaft F, coupling G, and spindle a revolving freely within the die 0, which is firmly held in position by the set-screw g.

By the revolution of the shaft F wire is coiled on the spindle a continuously, but is as continually forced off by the spiral face of the die 0. This result could not be accomplished if the spindle a were not cone-shaped, as shown in Fig. 3, because of the spring of the wire tending to increase the diameter of the coil. Slightly increasing the diameter of the spindle a at the end opposite to its shank compensates for this increase of diameter of the coil, whereby sufficient-friction is obtained to cause the wire to be continuously coiled.

In order to permit adjustment of the machine for open or close coiling, the die cis provided with a conical central holeor eye, for the purpose of permitting the same to be held at various angles on the spindle a.

Referring to Fig. 1, by moving the post 0, made adjustable, as hereinbefore stated, in any suitable manner, to the left, yet keeping the tool-carrier E in contact with the washer t, and this in contact with the coupling G, the angle of the spiral face of the die 0 with that of the spindle a will be increased, thus causing the wire to be coiled more open, a reverse adj ustment of the parts just named causing the wire to be coiled more closely. When coiling unannealed wire the pulley d is brought into closer contiguity with the die 0 by swinging the free end of the frame 1) toward the spindle a, when it may be secured in rosition by the screw h.

When it is desired to slightly increase the diameter of the coil, one or more washers, i, are placed on the spindle a, between the toolearrier E and coupling G, or a thicker one substituted for that already on or the washer may be removed entirely, when the coil will be correspondingly smaller in diameter, owing to the fact that by carrying the free end of the tool-carrier E toward the outer end of the spindle a the point at which the wire is coiled on the same will be slightly larger in diameter, and vice versa.

When making larger or smaller coils corresponding dies 0 and spindles a are used, or the die 0 may be removed altogether and a proper shape given to the tool-carrierE itself. I prefer, however, a hardened-steel or other metallic die made substantially in the form shown.

The shortest diameter of the bore of the die 0 is as long as the longest diameter of the conical portion of the mandrel a.

When used as a lathe attachment the man.- drel a is secured to the face-plate of a lathe, the arm E being secured to the tool-post of the same in like manner as the common lathe cutting-tools are secured.

The reel carrying the wire to be coiled is attached in any convenient manner.

Having thus described my invention, I claim. as new and desireto secure by Letters Patent-- 1. In a wire-coiling machine, the combination, with a shaft, F, and a tool-carrier, of a tapered spindle, at, whose smaller diameter is toward the shaft F, substantially as shown and described.

2. The combination, in a wire-coiling machine, of the tapered spindle a, spiral-faced die 0, and tool-carrier, substantially as and for the purpose set forth.

3. The combination, in a wire-coiling machine, of the tapered spindle a and spiralfaced die, having a conical central eye and means for adjusting the same, substantially as and for the purpose specified.

4.. The combination of the tapering spindle a, die c, tool-carrier E, frame I), and pulley 61, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE. GALE.
